Exclusively grown and bred in America, Supima cotton produces the longest fibers and represents the top 1% cotton in the world. We take these longest and finest fibers and weave them into a 1200 thread count sateen fabric to create the most resilient, softest, and most comfortable sheets on Earth. Each of our products is trademarked and stamped with a Supima cotton label to ensure genuine quality.

Snooze on a cloud with our cashmere-soft and luxurious 1200 thread count bedsheets. Featuring a rich sateen weave, our Supima sheets are super indulgent with a smooth and crisp texture, similar to the Egyptian cotton bedding found in five-star hotels. These top-rated sheets are thick, heavy, and voluminous—but don't be fooled, as they are also ultra-breathable and cooling, making them perfect for year-round use.

Our fitted bedsheet has one of the best fits, with an extra deep pocket (18 inches) that easily accommodates Cal King adjustable mattresses, and premium elastic that goes all around for a snug fit. Head/foot tags make it easy to make the bed. The Supima cotton Cal King size sheet set includes 4 pieces: 1 Flat Sheet (102" x 108"), 1 Fitted Sheet (72" x 84" + 16"), and 2 Pillowcases (21" x 41").

Supima is a rare, premium natural and pure fiber that is twice as strong as cotton—making it extremely resilient to wear and tear. We add our secret sauce to the formula: Mercerization, which makes the luxury cotton sheets softer, vibrantly colored, and resistant to pilling, fading, and shrinkage. You can wash the Supima cotton sheets in a machine on a gentle cycle, and they will only get more comfortable and softer after every wash.

Looking to make your loved ones feel special? Consider our 1200 thread count Supima Cotton sheet sets, which are soft, cool, and the most comfortable sheets you'll ever sleep on. Pair them up with 1200 thread count pillowcases from Carressa Linen's home decor lux collection. If you ever want to exchange or refund the items, reach out to us on Amazon within 30 days of purchase, and we'll get that sorted for you!
